# Quality

Quality is one of the three OEE components and shows what proportion of the produced quantity meets quality requirements.

{% hint style="info" %}
What quality means in the OEE context and how it is calculated is explained under [Quality (Concepts)](https://docs.enlyze.com/en/concepts/understanding-oee/quality).
{% endhint %}

## Prerequisites

For ENLYZE to calculate quality, the following data must be available:

* **Performance tracking** is set up (see [Setting up OEE tracking](https://docs.enlyze.com/en/production-optimization/oee))
* **Order data** is connected to ENLYZE (see [IT-Connectivity](https://docs.enlyze.com/en/connect/it-connectivity))
* **Good quantity or scrap quantity** is reported per order

## Tracking good quantity and scrap

ENLYZE calculates raw material consumption from throughput and runtime of an order. Depending on which data is available, there are two paths to quality calculation:

**Good quantity is reported**\
ENLYZE calculates scrap as the difference between raw material consumption and good quantity.

**Scrap is reported**\
ENLYZE optionally distinguishes between startup scrap and running scrap, provided this distinction exists in the source system. The good quantity is calculated as raw material consumption minus scrap quantity.

The type of quality data tracking is determined during integration. Contact your ENLYZE representative to discuss the appropriate configuration.

## Quality in the app

The quality KPI is shown in several places in the ENLYZE App:

* **Order details**: For each order, good quantity, scrap, and quality factor are displayed.
* **Product overview**: The material overview shows lot size and scrap across all orders of a product (see [Setup sheet](https://docs.enlyze.com/en/setup-sheet#material-overview)).
* **Home screen**: The OEE summary includes the quality factor.
